Background. Stroke remains one of the most common noncommunicable diseases among Indonesian populations. This study aimed to identify the prevalence of stroke and its associated risk factors in the Sleman District of Yogyakarta Special Region, Indonesia. Method. This study was a secondary analysis of community-based data collected by the Sleman Health and Demographic Surveillance System (HDSS) in 2016. Basic demographic and socioeconomic data were collected. Additional questions about history of stroke and other chronic diseases were interviewed as a self-reported diagnosis. History of hormonal contraceptives use and dietary patterns were also collected. We examined the association between the prevalence of stroke and risk factors, namely, age, gender, self-reported history of chronic diseases, hormonal contraceptives use, and high-risk dietary patterns. Results. The survey included 4,996 households composed of 20,465 individuals. Data regarding stroke incidents were available from 13,605 subjects aged ≥20 years old. Among them, a total of 4,884 subjects also have data regarding stroke risk factors. The overall prevalence of stroke in Sleman District was 1.4% (0.5% men and 0.90% women). The prevalence increased with additional decades of age (p<0.001). In a multivariable model, increasing age, self-reported history of hypertension (OR=8.37, 95%CI: 4.76 to 14.69), and self-reported history of diabetes mellitus (OR=2.87, 95%CI: 1.54 to 5.35) were significantly associated with stroke. Conclusions. A community-based survey in Indonesia showed a high prevalence of stroke which was associated with increasing age, hypertension, and diabetes mellitus. These findings suggest that preventive actions against the aforementioned modifiable risk factors should be prioritized.

Duchenne muscular dystrophy (DMD), a progressive muscle-wasting disease, is mostly caused by exon deletion mutations in the DMD gene. The reading frame rule explains that out-of-frame deletions lead to muscle dystrophin deficiency in DMD. In outliers to this rule, deletion junction sequences have never previously been explored as splicing modulators. In a Japanese case, we identified a single exon 45 deletion in the patient's DMD gene, indicating out-of-frame mutation. However, immunohistochemical examination disclosed weak dystrophin signals in his muscle. Reverse transcription-PCR amplification of DMD exons 42 to 47 revealed a major normally spliced product with exon 45 deletion and an additional in-frame product with deletion of both exons 44 and 45, indicating upstream exon 44 skipping. We considered the latter to underlie the observed dystrophin expression. Remarkably, the junction sequence cloned by PCR walking abolished the splicing enhancer activity of the upstream intron in a chimeric doublesex gene pre-mRNA in vitro splicing. Furthermore, antisense oligonucleotides directed against the junction site counteracted this effect. These indicated that the junction sequence was a splicing silencer that induced upstream exon 44 skipping. It was strongly suggested that creation of splicing regulator is a modifier of dystrophinopathy.

This study aimed to determine the effectiveness of gotu kola (Centella asiatica) in improving cognitive function in patients with vascular cognitive impairment (VCI). This study uses a quasi-experimental design. Subjects in this study were patients with poststroke cognitive impairment who were treated at two hospitals in Yogyakarta, Indonesia. The number of subjects was 48: 17 subjects were treated with 1000 mg/day of gotu kola extract, 17 subjects treated with 750 mg/day of gotu kola extract, and 14 subjects treated with 3 mg/day of folic acid for 6 weeks. A Montreal Cognitive Assessment-Indonesian version (MoCA-Ina) was conducted at the beginning of treatment and after 6 weeks of therapy. It was found that all trials effectively improved poststroke VCI based on MoCA-Ina scores over the course of the study. There is no significant difference in ΔMoCA-Ina (score at the 6th week of treatment − score at the beginning) mean score among the three groups, indicating that gotu kola is as effective as folic acid in improving poststroke VCI. Gotu kola was shown to be more effective than folic acid in improving memory domain. This study suggested that gotu kola extract is effective in improving cognitive function after stroke.
